Global warming resulting from greenhouse gas emissions will become an even greater issue in the future. It is the responsibility of the global community to save our planet for future generations. There are several effective technologies available for reducing greenhouse gas emissions such as fuel switching, renewable energy, and Carbon Capture Storage (CCS). CCS can be applied where fossil fuels are used to generate energy. An alternative storage for CO2 instead of coal beds, deep sea, or depleted reservoirs is in saline aquifers that have a huge capacity for storage. Several countries like Canada and Norway have already initiated pilot projects to store CO2 in saline aquifers. Indonesia has potential for using saline aquifers in Sumatra and east Kalimantan. This paper will present results of laboratory and simulation studies to examine the capacity of CO2 storage in saline aquifers.Using a black oil reservoir simulator, a model was built with CO2 properties, PVT, and field reservoir properties excluding CO2 mineralization and carbonization. Injection of CO2 was simulated over several decades. The storage capacity of the model is 1.277 x 1010 Sm3 that was filled by 1.24 x 1010 Sm3 of injected CO2. The results of the simulations are useful to better understand the capacity of saline aquifers for CO2 sequestration in Indonesia.
